2016 grizzly Engine failure

Hello everyone, was at my dealer today and sadly there was not one but two 2016 grizzlies with engine failure, the suspected cause both grizzlies sucked in dust, I believe this was talked about on a earlier thread, the small foam filter gasket ahead of the main air filter aloud dust into the engine, they were never oiled and greased from factory on the end for a good seal, both engines were still running but were smoking bad, if you had not oiled and greased this filter gasket on yours yet I would do it right away, just a friendly reminder. thanks
